Re: Kensington Metropark, Michigan

The north/south dividing line corresponds to the floristic tension zone. It is set partly by temperature for the range edge of southern species, and by soils for the relative dominance of the “northern” species. It is purported to be the area of greatest turnover between northern and southern (centr...

Re: Beginning of the end for hardwood here?

Wood is wasteful as solar energy battery, except in a functioning ecosystem where thousands of species take their cut and maintain system stability. Plus you end up burning up the battery. Ideally, one would cut out the middleman and capture solar energy more directly. But we should not do any this ...

Re: Russ Forest Lidar

...the north woods ... I would guess second growth... no White Pines? Larry Larry, "North woods"? I had to drive south from Grand Rapids to get there;) What we call the "north woods" is too cold for tuliptree to grow naturally. Though I did see one planted in Rose City, Michigan, east of Houghton L...

Re: Russ Forest Lidar

what method and equipment are you using to measure tree height, if I may ask? Bob, I have a Nikon Forestry Pro. I suspect the Doug's accuracy is greater on account of a few things. I know that when standing in at a given spot, my device seems report a certain set of exact values, implying that eith...

Re: Russ Forest Lidar

Stay tuned. Doug may likely post more photos and more precise (official) estimates of the trees at this superlative site, sometime later. I suspect his numbers to be more accurate than mine. Upon looking at the Lidar again, I think that it was pretty spot on. I doubt that any tree here is yet above ...

Re: Russ Forest Lidar

Currently, I don't know the ages. I interpret the size, structure, and down wood as possibly close enough to be labelled old growth. But whether it had ever been logged I don't know. Unless there are obvious stumps and invasive species, or a plow layer, it wouldn't make much of a difference at this ...

Re: Russ Forest Lidar

Doug and I visited Russ Forest on March 3, 2018 to look for those tall trees. The uneven canopy with gaps in the east had red oak, black oak, and bitternut. The area of uniform canopy at about 30 m in height on the west was beech and sugar maple. The emergent trees in either area were tuliptrees. 20...

Re: Russ Forest Lidar

I'll have to find where these often cited metroparks are and look at their LiDAR canopy heights. SE Michigan has full LiDAR coverage.

Re: Russ Forest Lidar

Any notable tree that happens to be near a field site, I will attempt a measurement, if I am aware of it. Officially, that could be anywhere in the Lower Peninsula down to northwest Indiana, east to northwest Pennsylvania. That said, my fieldwork has been fairly limited in range range in the last fe...
